Lulli was possessed during his life but by one thought, and that was, to combat and convert the infidels.[65] It was upon the proposition of this zealous missionary that the council of Vienna decided that chairs should be established in the universities of Rome, Bologna, Paris, and Salamanca, for instruction in the languages of the East. He presented to the pope several memorials upon the means of annihilating the worship of Mahomet and the domination of his disciples. Lulli, constantly occupied with his project, made a pilgrimage into Palestine, travelled through Syria, Armenia, and Egypt, and came back to Europe to describe the misfortunes, the captivity, and the disgraces of the Christians beyond the seas. On his return, he visited all the courts of the West, seeking to communicate to sovereigns the sentiments by which he was animated. Finding his efforts were vain, his zeal carried him to the coast of Africa, where he endeavoured to convert by his eloquence those same Saracens against whom he had invoked the arms of Christian warriors. He returned to Europe, passed through Italy, France, and Spain, preaching everywhere the necessity for another crusade. He embarked again for Jerusalem, and brought back, as the fruit of his pilgrimage, some useful notions upon the best manner of attacking the countries of the infidels. All his labours, all his researches, all his prayers, produced no effect upon the indifference of kings and nations. Lulli, at length despairing of seeing his projects realised, and deploring the blindness of his contemporaries, retired to the island of Majorca, which was his native country. From the depth of his retreat he still issued memorials upon an expedition to the East; but solitude soon wearied his ardent and restless spirit, and he quitted Majorca, no more to waste his words upon the princes of Europe, who would not listen to him, but to return to the Mussulmans, whom he still hoped to lead to the Gospel by his eloquence. He repaired a second time to Africa, and at length suffered, as the reward of his preachings, the torments and the death of martyrs.
